Description

Technical Field

[0001] This invention relates to a pin-type precision garlic planter, belonging to the field of agricultural machinery technology. Background Technology

[0002] Currently, garlic planting mainly relies on manual labor, which is extremely inefficient. Although garlic planting equipment on the market can improve planting efficiency, it generally suffers from complex structures and low germination rates.

[0003] A key factor in achieving high germination rates in garlic cultivation is ensuring that the bulbils face upwards during the planting process. However, existing garlic cultivation equipment cannot guarantee that the majority of the garlic bulbs will face upwards, nor can it ensure that every planting hole contains garlic bulbs, or that some garlic bulbs will not be in the planting hole. This results in low germination rates and high costs. Summary of the Invention

[0004] The present invention aims to solve the problems of high cost and low germination rate caused by the complex and limited structure of existing garlic planters, and to provide a pin-type precision garlic planter with optimized structure that can improve the germination rate of garlic planting, reduce losses and lower costs.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: A pin-type precision garlic planter, comprising a frame, is characterized in that the frame is equipped with a seed bin, a conveying system, a vision recognition component, a pin-inserting mechanism, and a planting system; wherein... The seed bin is used to store garlic cloves; The conveying system is used to remove garlic cloves from the seed bin and transport them to the needle insertion mechanism; The visual recognition component is used to identify the position of the garlic cloves in order to control the insertion mechanism to insert the garlic cloves. The needle insertion mechanism is used to insert and transfer garlic to the sowing system; The sowing system is used to plant garlic cloves into the soil.

[0006] Furthermore, the conveying system includes a first chain drive mechanism, a clutch mechanism, a second chain drive mechanism, a material distribution conveying mechanism, and a straightening conveying mechanism; The first chain drive mechanism is used to transmit the power of the wheel to the clutch mechanism, including a first driving gear mounted on the wheel axle, a first driven gear mounted above the frame and corresponding to the position of the first driving gear, and a first chain driving between the two gears; The clutch mechanism is configured between the first chain drive mechanism and the second chain drive mechanism to engage or disengage the connection between them. It includes a main clutch shaft and a driven clutch shaft, a driving engagement gear mounted on the main clutch shaft and a driven engagement gear fixed on the driven clutch shaft. A clutch control plate with a clutch lever is fixedly mounted on the driven clutch shaft. A clutch gear is mounted on the clutch control plate. One side of the clutch gear is in a fixed engagement state with the driven engagement gear. The other side of the clutch gear can engage or disengage with the driving engagement gear under the operation of the clutch lever. The second chain drive mechanism is used to transmit the output torque of the clutch mechanism to the material distribution and conveying mechanism. It includes a second driving gear fixed on the clutch shaft, a second driven gear fixed on the drive shaft of the material distribution and conveying mechanism, and a second chain that drives between the two gears.

[0007] Furthermore, the material distribution and conveying mechanism is used to remove garlic cloves one by one from the seed bin and arrange them into their respective conveying tracks. It includes several conveying chains, three drive shafts, and several conveying gear sets. One drive shaft serves as the drive shaft of the material distribution and conveying mechanism and is located below the frame, connected to the first chain drive mechanism. The other two drive shafts are horizontally arranged above the frame. Several conveying gear sets are axially distributed on the three drive shafts at predetermined intervals. Each conveying gear set has three gears, which are respectively installed on the three drive shafts. Several conveying chains are respectively driven and connected to several conveying gear sets, and multiple garlic spoons are installed on each conveying chain at predetermined intervals.

[0008] Furthermore, the corrective conveying mechanism is used to adjust the shape of the garlic cloves for insertion and removal. It includes four V-shaped guide slides configured on the frame and four conveyor belts arranged below the V-shaped guide slides. The V-shaped guide slides are inclined at a certain angle, with their upper ends connected to the discharge end of the material dispensing and conveying mechanism and their lower ends close to the surface of the conveyor belts. The middle part of the conveyor belts is configured with positioning grooves that can receive and accommodate the garlic cloves.

[0009] Furthermore, the visual recognition component includes several image recognition sensors configured at the discharge end of the corrective conveying mechanism. The image recognition sensors are used to accurately identify the position and orientation of garlic cloves and transmit the identified garlic clove shape and position signals to the needle insertion mechanism.

[0010] Furthermore, the needle insertion mechanism includes a transverse cylinder mounted on the frame, a lifting cylinder connected to the output of the transverse cylinder, and a swing motor connected to the output of the lifting cylinder. The output of the swing motor is connected to an L-shaped swing arm. The lower end of the L-shaped swing arm is connected to a syringe via a rotating motor. The end of the syringe has two needles.

[0011] Furthermore, the seeding system includes a pair of opposing linkage mechanisms, a crossbeam connecting the two linkage mechanisms, and several duckbill-type soil-inserting mechanisms fixed on the crossbeam. The linkage mechanisms are configured on the uprights on both sides of the frame and include a swing rod connected by a motor output. The swing rod is connected to the linkage through a rotating shaft. A slider is rotatably installed below the linkage. The slider is adapted to slide in the groove of the upright. The two ends of the crossbeam are respectively connected to the sliders on the left and right sides.

[0012] Furthermore, the duckbill-type soil-inserting mechanism is fixed to the crossbeam via two mounting arms. It includes a receiving hopper, a pair of oppositely arranged and mutually compatible semi-conical planting nozzles, and an opening / closing motor for controlling the opening and closing of the two nozzles. The receiving hopper is fixed in the middle of the two mounting arms and is designed as a vertically continuous square groove. The hopper has an outwardly expanding upper opening, with a slender needle-retracting channel extending downwards along one side of the upper opening. The two semi-conical planting nozzles are mounted on both sides of the receiving hopper via their respective rotating shafts. When they are closed relative to each other, a cone-shaped hopper is formed below the receiving hopper; when they are expanded relative to each other, a discharge channel is formed below the receiving hopper. The opening / closing motor is fixed to the outside of the receiving hopper via a connecting frame. A torsion opening arm is mounted on the output shaft of the opening / closing motor. The two ends of the torsion opening arm are connected to the two semi-conical planting nozzles on both sides. The forward or reverse rotation of the opening / closing motor enables the torsion opening arm to rotate in either direction, thereby causing the two semi-conical planting nozzles to close or open relative to each other.

[0013] Furthermore, a discharge channel is provided on one side of the seed bin to connect with the conveying mechanism. The two sides of the discharge channel are respectively inserted and fixed to two pre-formed guide baffles on the frame. The channel formed between the two guide baffles is used to distribute garlic cloves. A soft steel brush is installed at the bottom of the channel.

[0014] This invention discloses a pin-type precision garlic planter, primarily focusing on improving the survival rate and planting efficiency of garlic. Through the coordinated operation of visual recognition technology and a pinning mechanism and a duckbill-type soil-inserting mechanism, the planter maintains the shape of the garlic seed during planting. The visual recognition technology identifies the garlic buds, and the pinning mechanism ensures the buds are placed vertically into the duckbill clamp designed to maintain the garlic's soil-insertion posture. This optimizes the overall structure of the device, ensuring that the vast majority of garlic buds face upwards during planting, thus solving the problem of low germination rates caused by incorrect bud orientation. Regarding planting efficiency, this invention employs multiple interconnected transmission and conveying mechanisms to separate the garlic cloves individually. The rotation and movement control of the pinning mechanism utilizes a combination of cylinders and motors, further improving planting efficiency. Attached Figure Description

Detailed Implementation

[0016] The invention will now be described in detail with reference to the accompanying drawings.

[0017] Example 1 A pin-type precision garlic planter, such as Figure 1 As shown, it includes a frame 1 and a seed bin 2, a transport system, a vision recognition component 4, a needle insertion mechanism 55 and a seeding system 66 configured on the frame 1.

[0018] The frame 1 is a mechanically integrated frame, with its bottom fixed to the wheel axles, and four wheels installed at both ends of the axles. The seed bin 2 is used to hold garlic cloves and is located at the rear end of the frame 1. A discharge trough is provided on one side of its front end to connect with the conveying mechanism.

[0019] The two sides of the discharge channel of the seed bin 2 are respectively inserted and fixed to two pre-formed guide baffles 11 of the frame 1. The channel formed between the two guide baffles 11 is used to distribute garlic cloves. A soft steel brush is installed at the bottom of the channel.

[0020] The transportation system is as follows Figure 2 As shown, it includes a first chain drive mechanism 31, a clutch mechanism 32, a second chain drive mechanism 33, a material distribution conveyor mechanism 34, and a straightening conveyor mechanism 35, all configured on the frame 1; wherein: The first chain drive mechanism 31 is used to transmit the power of the wheel to the clutch mechanism 32, including a first driving gear 311 mounted on the wheel axle, a first driven gear 312 mounted above the frame and corresponding to the position of the first driving gear 311, and a first chain 313 driven between the two gears.

[0021] The clutch mechanism 32 includes a main clutch shaft and a driven clutch shaft, a driving engagement gear 321 mounted on the main clutch shaft, and a driven engagement gear 322 fixed on the driven clutch shaft. A clutch control plate 324 with a clutch operating lever 323 is fixedly mounted on the driven clutch shaft. A clutch gear 325 is mounted on the clutch control plate 324 via bearings. One side of the clutch gear 325 is in a fixed engagement state with the driven engagement gear 322. The other side of the clutch gear 325 can be engaged or disengaged with the driving engagement gear 321 under the operation of the clutch operating lever 323. When power needs to be supplied to the conveying system via the wheels, the clutch control plate 324 is rotated by the clutch lever 323, causing the clutch control plate 324 to rotate to the side of the clutch gear 325 and engage with the active meshing gear 321. At this time, the first chain drive mechanism 31 and the second chain drive mechanism 33 are connected, thereby transmitting power from the wheels to the material conveying mechanism 34. When the equipment needs to move independently without starting the conveying system, the clutch control plate 324 is rotated by the clutch lever, causing the clutch control plate 324 to rotate to the side of the clutch gear 325 and disengage from the active meshing gear 321. This disconnects the first chain drive mechanism 31 and the second chain drive mechanism 33, and the wheels only provide the function of moving.

[0022] The second chain drive mechanism 33 is used to transmit the output torque of the clutch mechanism 32 to the drive shaft of the material distribution and conveying mechanism 34. It includes a second driving gear 331 fixed on the clutch shaft, a second driven gear 332 fixed on the drive shaft of the material distribution and conveying mechanism 34, and a second chain 333 driven between the two gears. The material distribution and conveying mechanism 34 is used to remove garlic cloves one by one from the seed bin 2 and send them into their respective conveying tracks. It includes four conveying chains 341, three drive shafts 342, and four conveying gear sets. One drive shaft 342 is configured as the drive shaft of the material distribution and conveying mechanism 34 and is located below the frame 1, connected to the first chain drive mechanism 31. The other two drive shafts 342 are horizontally arranged above the frame, one at the discharge end of the seed bin 1 and the other at the feed end of the straightening conveying mechanism 35. The four conveying gear sets are axially distributed on the three drive shafts 342 at a predetermined interval. Each conveying gear set has three gears, which are respectively installed on the three drive shafts 342. The four conveying chains 341 are respectively connected to the four conveying gear sets, and multiple garlic spoons 343 are installed on each conveying chain 341 at a predetermined interval.

[0023] The corrective conveying mechanism 35 is used to adjust the shape of the garlic cloves for insertion. It includes four V-shaped guide slides 351 mounted on the frame 1 and four conveyor belts 352 arranged below the V-shaped guide slides 351. The V-shaped guide slides 351 are inclined at a certain angle, with their upper ends connected to the discharge end of the material distribution conveying mechanism 34 and their lower ends close to the surface of the conveyor belts 352. The middle part of the conveyor belts 352 is provided with positioning grooves 353 that can receive and accommodate the garlic cloves.

[0024] The visual recognition component 4 includes four image recognition sensors configured at the discharge end of the corrective conveying mechanism 35. The image recognition sensors are used to accurately identify the position and orientation of garlic buds and transmit the identified garlic clove shape and position signal to the needle insertion mechanism 5.

[0025] The needle insertion mechanism 5 includes a transverse cylinder 51 mounted on the frame 1, a lifting cylinder 52 connected to the output of the transverse cylinder 51, and a swing motor 53 connected to the output of the lifting cylinder 52. The swing motor 53 is connected to an L-shaped swing arm 54. The lower end of the L-shaped swing arm 54 is connected to a syringe 56 via a rotary motor 55. The end of the syringe 56 has two needles. When the garlic cloves are delivered to the needle insertion position via the conveyor belt 352 of the straightening conveyor mechanism 35, the rotary motor 55 controls the syringe 56 to rotate to adjust the needle position, the swing motor 53 controls the L-shaped swing arm 54 to swing to adjust the needle angle, the transverse cylinder 51 drives the lifting cylinder 52 to the pre-insertion position, and finally the lifting cylinder 52 moves downward, driving the lower needles to complete the garlic clove insertion action.

[0026] The sowing system 6 includes a pair of opposing linkage mechanisms 61, a crossbeam 62 connecting the two linkage mechanisms 61, and four duckbill-type soil-inserting mechanisms 63 fixed on the crossbeam 62. The linkage mechanism 61 is arranged on the uprights 12 on both sides of the frame 1, including a swing rod 611 connected by a motor output. The swing rod 611 is connected to the linkage 612 through a rotating shaft. A slider is rotatably installed below the linkage 612. The slider is adapted to slide in the groove 613 of the upright 12. The two ends of the crossbeam 62 are respectively connected to the sliders on the left and right sides. The duckbill-type soil-inserting mechanism 63 is fixed to the crossbeam 62 by two mounting arms 631 on both sides. It includes a receiving hopper 632, a pair of oppositely arranged and mutually adapted semi-conical planting nozzles 633, and an opening and closing motor 634 for controlling the opening and closing of the two planting nozzles 633. The receiving hopper 632 is fixed in the middle of the two mounting arms 631. Its structure is designed as a square groove that runs vertically through the top and bottom. The receiving hopper 632 has an outwardly flared upper opening, and a slender needle-retracting channel 632b is opened downward along one side of its upper opening. The two semi-conical planting nozzles 633 are mounted on both sides of the receiving hopper 632 by their respective rotating shafts. When they are closed relative to each other, a cone-shaped hopper is formed below the receiving hopper 632. When they are expanded relative to each other, a discharge channel is formed below the receiving hopper 632. The opening and closing motor 634 is fixed to the outside of the receiving hopper 632 by a connecting frame. The output shaft of the opening and closing motor 634 is equipped with a torsion opening arm 635. The two ends of the torsion opening arm 635 are respectively connected to the semi-conical planting nozzles 633 on both sides. By turning the opening and closing motor 634 forward and reverse, the torsion opening arm 635 can be rotated in the forward or reverse direction, thereby driving the semi-conical planting nozzles 633 on both sides to close or open relative to each other.

[0027] The design principle and planting process of the pin-type precision garlic planter in this embodiment are as follows: First, after all garlic cloves are separated, they are placed into the seed bin. During the planter's movement, the material distribution and conveying mechanism 34 operates via a first chain drive mechanism 31, a clutch mechanism 32, and a second chain drive mechanism 33, all linked to the wheels. At this time, the conveying chain 341 of the material distribution and conveying mechanism 34 uses its installed garlic scoop 343 to remove garlic cloves from the seed bin and transport them to the V-shaped guide slide 351 of the straightening conveying mechanism 35. The shape of the V-shaped guide slide 351 ensures the garlic cloves are approximately parallel to it. The garlic cloves fall through the V-shaped guide slide 351 into the positioning groove 353 in the middle of the conveyor belt 352. When the conveyor belt 352 transports the garlic cloves to the vision inspection station, the image recognition sensor of the vision recognition component monitors the position, angle, and shape of the garlic seeds and controls the actions of the cylinders and motors of the pin insertion mechanism 5 based on the monitored signal data to obtain the optimal pin insertion angle and position. After the needle insertion mechanism 5 picks up the garlic cloves, it is transferred to the duckbill-type soil insertion mechanism 63 of the sowing system. After the needle extends into the receiving hopper 632, it exits through the needle withdrawal channel 632b on one side of the receiving hopper 632. At this time, the garlic cloves enter the receiving hopper 632 in a predetermined shape and enter the cone formed by the two semi-conical planting nozzles 633. Then, the motor controls the linkage mechanism 61 to move, so that the duckbill-type soil insertion mechanism 63 on the crossbeam 62 is inserted into the soil to a predetermined depth. Then, the opening and closing motor 634 controls the two semi-conical planting nozzles 633 to open, so that the garlic cloves are planted in the soil to complete the sowing. Then, the motor controls the linkage mechanism 61 to move, so that the duckbill-type soil insertion mechanism 63 on the crossbeam 62 is lifted upward, while the opening and closing motor 634 rotates to control the two semi-conical planting nozzles 633 to close.

[0028] Compared with traditional equipment, the pin-type precision garlic planter of this embodiment has the following structural advantages: 1. A material distribution and conveying mechanism is configured at the discharge end of the seed bin. The garlic cloves are separated one by one by the conveying chain and garlic spoon of the material distribution and conveying them to the positioning groove on the conveyor belt of the straightening conveyor mechanism, and then conveyed to the needle insertion station by the conveyor belt.

[0029] 2. The pinning mechanism is composed of a cylinder, a motor, and pins, which greatly improves the freedom of the pins in multiple directions, making movement and shape transformation more flexible. Using double pins to fix the garlic cloves makes it easy to identify the direction of the garlic bulbils. After determining the direction, the double pins are used to maintain the shape of the garlic cloves, ensuring the garlic bulbils are planted vertically.

[0030] 3. By utilizing artificial intelligence visual recognition technology to identify garlic buds, the garlic bud tip and root plate tip can be quickly and reliably distinguished, providing key visual guidance for automated garlic planting and directional sorting equipment, and improving operational efficiency and accuracy.

[0031] 4. The sowing system combines a linkage mechanism and a duckbill-type soil-inserting mechanism to maintain the garlic bulbs in a vertically upward sowing state to the greatest extent possible, resulting in more accurate directional control.
